MACHINE FOR MAKING COILED-WIRE FABRIC.

SPECIFICATION forming part of Letters Patent No. 688,844, dated December 17', `1901. Application filed August 28, 1901. Serial No. 73,562. (No model.)

To @ZZ whom t may concern:

Beit known thatI, JOHN F. GAIL, a citizen of the United States, residing at Kenosha, in the county of Kenosha and State of Wisconsin, have invented certain new and usefulImprovements in Machines for Making Ooiled- Wire Fabric; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had lto the accompanying drawings, and toletters of reference marked thereon, which form a part of this specification.

My invention relates particularly to machines for the manufacture of such coiledwire fabrics as are used in the manufacture of woven-wire bed-bottoms. With such machines the coils are formed ^by pushing the wire through a spiral die, and the fabric is formed by rotating and progressing the new coil longitudinally, so as to cause it to intertwine at each rotation with the last preceding coil, and my invention is specially, though not exclusively, adapted toembodiment in automatic machines for the making of such fabrics.

The first and chief object of my invention is to meet the commercial demands for a more rapid machine than those heretofore in use in this art.

A second object of my invention and one that is attained incidentally with the attainment of the Iirstis the greater uniformity in the product of the machine and the red uction of waste of wire.

A third object of my invention is the production of a machine requiring a minimum of skilled attendance. y

For commercial reasons it is desirable to operate such machines at a relatively high Speed. Such high speed has long been sought. This is attested by the history of experiments in various factories and by the prior patents relating to this art. I-Ieretofore such machines have not in daily practice woven more than thirty-five fabrics of average size in a day of ten hours. With machines embodying the improvement Set forth in this application and the improvements described by Xed upon the power-shaft.

me in two other applications eighty .such fabrics per day of ten hours have been and arc being woven in daily practice and with less trouble than heretofore, and I believe that a proportionate Share of said increase of production is due to the improvement herein described. The machine is now operated at a higher rate of speed and the stops due to defective operation are now less frequent and of shorter duration.

The above-mentioned objects are attained in part by improved mechanism for stopping the operation of the machine when abnormal action takes place. Said mechanism is made the subject-matter of this application. Such stopping of the machine may be divided into two factors or steps--irst, the removing of the power by which the machine is driven; second, the overcoming of the momentum of the various moving parts of the machine in order that idle movement, on account of the momentum remaining after the power has .been taken off, may be prevented. When the operation of the machine becomes abnormal, the prompt renewal of power and the simultaneous overcoming of the momentum of the moving parts of the machine are of great importance, for the sooner the operation is completely arrested the less wire will be wasted and the less difficult it will be to remove the wire which has been driven abnormally, and the less the fabric already made becomes disarranged or detached from the mechanism, which normally supports it and keeps the last-finished coil in the coil-receiving o channel.

Power is transmitted to the machine by an Ordinary belt applied to an ordinary pulley Alongside of said p ulley is an ordinary idle pulley, to which the belt is shifted when the power is to be again shifted from the machine. A beltshifter resembling the ordinary manual beltshifter is applied to these pulleys and belt.

In addition to said shifter an automaticbrake 9 is located adjacent to the power-pulley and held out of engagement with said pulley by mechanism which is released by apparatus actuated through the abnormal action of the coil or of the wire which is to form the coil.

IOC)

. ism.

Electric mechanism for automatically controlling said brake and belt-shifter is herein described. y

Sometimes the abnormal action of the wire consists in entanglement or binding of the wire on or adjacent to the spool supplying the wireto the machine, so that the wire will not unreel or deliver at all or only under great strain. Sometimes this strain is so great as to break the wire, and sometimes it is so great as to cause the wire to slip in the coil-forming mechanism. When the latter occurs, only a partial coil will be formed by the time the cutting and fabric-shifting apparatus operatie, and the part of the margin of the fabric to which said coil does not eX- tend is then in danger of becoming detached from the fabric-holding mechanism. To stop the operation of the machine under such abnormal action, I have placed immediately following the spool a circuit-closing apparatus which is actuated by excessive tension on the wire coming from thc reel; but the circuit-closing mechanism last described is not operative when the progression of the wire stops without abnormal tension. Between the last-mentionedmechanism and the forcing-rolls of the coil-forming mechanism I have located another circuit-closing mechanism, which always closes the circuit when the movement of the wire toward the coil-forming mechanism ceases or becomes abnormally slow; but during the operation of the machine there are intervals (from the completion of a coil until the cutting of said coil and the shifting of the fabric are completed) when the wire stops normally. The circuit-closing mechanism last described closes the circuit during said normal stopping ofthe wire as well as when the wire stops abnormally adjacent to said mechan- To prevent the machine from being stopped during the normal stopping of the Wire, I have associated with the last-mentioned circuit-closing mechanism a circuitbreaking mechanism which serves to break the circuit during the period when the last iinished coil is beingr cut and shifted. Then t-he effect of said circuit-closing device is nullied by said circuit-breaking device.

Sometimes the movement of the wire from` the spool to and through the forcing-rolls of the coil-forming mechanism is normal; but the wire breaks immediately after passing between said rolls, and the end ot' said wire instead of entering the coil-forming dies is turned laterally and runs wild. Such abnormal action does not influence the two vcircuit-closing devices already mentioned. To close the circuit through such abnormal action, another circuit-closing device is placed adjacent tothe coil-forming mechanism and in such position as to be reached by the loose Wire running from the coil-forcing rolls. In some cases the action is abnormal after the wire issues in the form of a coil from the coil-forming mechanism and before reaching the coil-receiving mechanism or the coil-guide preceding the coil-receiving mechanism. If the resistance met by the coil in the coil-guide or the coilreceiving mechanism becomes excessive, then the coil between the coil-forming mechanism and the coil-guide bends or buckles laterally and ceases to pass into the coil-receiving mechanism. To aid in stopping the machine when this occurs, I have placed between the coil-forming mechanism and the coil-receiv ing mechanism a circuit-closing device which is actuated by the coil when the latter leaves its normal path, as above described. wWhile the drawings show said circuit-closing devices upon the same circuit, it is to be understood that they may be placed upon separate circuits, each suitably connected with the beltshifting mechanism.

In the accompanying drawings, Figure 1 is a front elevation of a portion of a machine embodying my improvement. Fig. 2 is a plan of thesame portion of said machine. Fig. 3 is a diagram showing the electric circuit andthe relative arrangement of the circuit-closing and circuit breaking devices and the mechanism for shifting the power-belt. Fig. 4 is an end elevation of the beltshifting and brake mechanism. Fig. 5 is an elevation of the belt-shiftingand brake mechanism. Fig. 6 is a transverse section of the brake. Fig. 7 is a front elevation of the circuit-closer controlled by the movement ot' the wire coming to the coil-forming mechanism. Fig. 8 is a side elevation of the same. Fig. 9 is a vertical section inthe line 9 9 of Fig. '7. Fig.i10 is an internal view of the lower wheel of said device. Fig. l1 is atransverse section in the line 11 11 of Fig. 8 looking in the direction of the arrow. Figs. 12 and 13 are details of the coil-guides for said device. Fig. 14n is an elevation, and Fig. 15 is a plan, illustrating mechanism for breaking the circuit when closed by said centrifugal circuitcloser during normal stopping of the Wire going to the coil-forming mechanism. Fig. 16 is an elevation, and Fig. 17 a plan, of the mechanism for closing the electric circuit when the coil between the coil-forming mechanism and the coil-guide in front of the coil-receiving mechanism leaves its normal path. Figs. 18 and 19 are detail views of the circuit-closing mechanism which is actuated by excessive tension on the wire leaving the reel or spool and going toward the coil-forming mechanism.

Referring to'Figs. 1 and 2, A is the frame of the machine; Bis the reel holding the wire B, from which the coils are to be formed. Said reel is suspended from brackets B2, extending horizontally from the frame A. The wire is led from the reel downward to the lower end of a tube B3, extending vertically through said reel. The wire passes upward through said tube and extends over an idle grooved wheel B4, supported on a horizontal i'ixed shaft B5. From said wheel a wire eX- tends to and around the friction-wheel B6. Thence the wire returns to the grooved wheel IIO B'1 and passes over the lower portion of the latter and thence upward over an idle inclined grooved wheel C. Thence it passes between the idle rollers D D' and thence between the 'forcing-rolls E E'. From said forcing-rolls the wire passes through a coil-forming die E2. From said coil-forming die the wire emerges as a coil and is projected forward into the coil-receiving mechanism F. It is to be remembered that all of the wire thus traced is moved by the forcing-rolls E E'. During the normal action of the machine said forcing-rolls draw the wire from the reel and force it through the coil-forming die until the coil extends through the coil-receiving mechanism to the margin of the fabric oppo` site the coil-termin g die. Then the said t'o rcing-rolls cease moving said wire and the knife F' sevels the coil, as is well known in this art. The said forcing-rolls rotate continually during the operation of the machine; but they are separated when the movement of the wire is to cease. Said rolls may, however, be arranged to stop when their action on the wire is to stop.

The wheel B6 is deeply grooved in order that the wire when it becomes slack will not readily leave said groove. Saidwheel is arranged to rotate upon a horizontal spindle B7, which is supported rigidly upon a vertical block B8. Said block is slidably mounted upon two parallel rods B9,which extend horizontally along the front edge of the frame of the machine, one of said rods being located above the other. From said block Baa bracket B10 extends toward the left and supports two vertical posts B11, which serve as additional guides for the wire, the latter passing between said posts. Immediately beneaththe block B8 is a small roller B12, the plane of which is parallel to the plane of the wheel B6. The axle B13 of said roller B12 is extended and attached rigidly to a rock-shaft B11, suitably supported beneath4 the frame of the machine parallel to the rods B11. The arm B15 extends downward from said rock-shaft, and a contracting spring B16 is joined by one end to said arm B15 and by the other end to a relatively xed point at the front of the machine. The tension of said spring is sufficient to hold the roller B12 in the notch bs, formed in the lower edge of the block B8, when there is no more than normal strain upon the wire going around the friction-wheel B6. Should the strain upon the wire become excessive, then the wire going around the wheel B1 will draw toward the left so hard as to cause the block BS to depress the wheel B12 and allow said block and wheel B11 to slide toward vthe left on the rods B11 B9. This brings the base of said block into contact with an electrode B11, supported by the frameA on the electric circuit leading to the belt-shiftingmechanism,whereby said circuit is closed and the brake and belt shifting mechanism actuated for the prompt stopping of the machine.

The circuit-controlling mechanism coming next in order is that which is to be operated when the coil-forming mechanism stops 0r moves at less than normal speed. A standard A' rises from the frame of the machine and supports a horizontal rigid spindle A2, upon which is mounted a loose roller D', the location of said roller D' being immediately beneath the path of the wire going from the wheel C to the forcing-rolls. Above the spindle A2 and parallel thereto is a groove A2, and above said groove adjacent to the righthand face or" said standard is an arch A4, and a vertical set-screw A5 extends downward through said arch. A bar D2rests within said groove A3 and is suitably hinged therein at its left end, so as to permit vertical movement at the right-hand end. At the free end of said bar there is a spindle AG, upon which is loosely mounted the roller D, said roller D being directly above the roller D' and bearing upon the wire B', passing over the roller D. Said set-screw is to be adjusted to limit the upward movement of said bar and to press said roller D downward to such extent as may be desired.

D3 is guide-tube for leading the wire B to the rollers D and D'. Said tube is secured by a set-screw d1 in a bracket D1, which extends into an opening D5 in the standard A'. A set-screw D0 extends through the standard A' to the bracket D1 and serves to bind said bracket in its proper position. The bracket D'1 is cylindrical, so that said tube D3 may be adjusted by rotating said bracket upon its axis or by shifting said bracket lengthwise. Said tube D3 is preferably provided with a tongue d3, extending between the rollers D and D', the vertical thickness of said tongue being slightly less than the diameter of the wire B, so that the roller D will not be in contact with said tongue when the wire B is in position between the roller D and the roller D'. When said wire is not between said rollers, the roller D will rest upon the tongue d2 and prevent said roller from touching said roller D'. The tubeD3 and its tongue are to be made of relatively soft metal in order to prevent wear of the wire B' and the faces of the rollers D and D', which latter are to be made of hardened steel and to be quite* smooth. By preventing the contact of the rollers D with the roller D' when the wire runs out from between said rollers the grinding of the faces of said rollers is prevented, and a continued rotation of the roller D', due to the added momentum of the roller D, is prevented.

Surrounding the spindle A2, between the roller D' and the standard A', is an annular electrode D1. Said electrode is suitably in sulated from the standard A' and the spindle A2 and roller D'. A circuit-wire D8 leads from said electrode. On the right-hand face of the roller D' are three centrifugal electrodes D, which are normally held outward by centrifugal action and one of which falls upon the annular electrode D7 when the ro- IOO l'IO

tation of said roller D' is less than normal.

` Each electrode D9 is secured to said roller D' bya screw-post D19, extendingloosely through one end of said electrode. The other end of said electrode is free, and its outward movement, due to centrifugal force, is limited by a post, The outer end of each electrode is turned away from the roller D sufficiently to extend over the annular electrode D7, so

that when said electrode D9 moves over the axis of the roller D it comes into contact with the outer face of said electrode. The operation of this circuit-closing device will now be readily understood. When the machine is in operation and the wire Bis running at its normal velocity between the rollers D D', the rotation of the roller D' is sufficiently rapid to cause said electrodes D9 to turn outward on account of centrifugal action away from the axis of said roller and out of contact with the annular electrode. If the wire ceases to run or if its velocity is reduced beyond the normal, centrifugal action is reduced, so that the electrode D9 then uppermost will fall into contact with the annular electrode D7, whereby the electric circuit leading to the belt-shifting mechanism is closed; but, as already hereinbefore stated, the movement of the wire toward the coil-forming mechanism is normally interrupted at the completion of each coil. Hence the closing of the circuit by the centrifugal electrodes on the said roller D' must at such times be counteracted by a circuit-breaking mechanism suitably timed to operate during the period when the wire normally ceases to move toward the coilforming'mechanism. Such circuit-breaking mechanism is next described.

G is a standard resting upon the frame A adjacent to a sprocket-chain H.

G is an electrode insulated upon the horizontal base g of the standard G. Said electrode is preferably extended laterally from its attachment, so that said extended portion may yield vertically. G2 is another electrode corresponding to the electrode G and also insulated upon said base and extending laterally over the lateral extension of the electrode G', rising, when free, above the electrode G', so that there is no contact between them. Both said electrodes are in a circuit leading to the belt-shifting mechanism.

G3 is a lever hinged in a vertical plane to the standard G and having at its lower end an insulation g3, which when said lever is in the upright position bears upon the electrode G2 and presses the latter downward upon the lower electrode G', whereby the circuit is closed at this point. This is the normal position of said lever. On said sprocket-chain H is a lug or similar device H', extending laterally, so that the upper end of the lever Gis in the path of said lug.l The movement of said chain is toward the right, and when said lug meets said arm the latter is turned upon its hinge, the upper end going toward the right and the insulation g2 going toward the left and upward sufiiciently to allow the electrode G2 to rise out of contact with the electrode G', whereby the circuit is broken at this point. The movement of said lug is so timed as to turn said lever simultaneously with the stopping of the wire when the coil has been completed, as will be hereinafter described. G4 is a standard similar to the standard G. It is located to the left of said standard and in the same relation to the chain H. The distance between the standard G and the standard G4 is equal to the distance traversed by the lug` H' during the interval when the wire is not ruiming. Attached to said standard G is a lever G5, similar to the lever G2, its upper end extending similarly into the path of the lug H'. From the lower end of the lever Ga link G9 extends to the upper portion of the lever G3, each end of said link being suitably coupled to the adjacent lever at about the same distance from the axis of the adjacent lever. Being thus coupled by said link, said levers must turn upon their axes in unison when the lever G2 is upset by the passing of the lug H', and the link G(i is shifted towaid the right and made to turn the lever G5 into the upright position. By the time that the lug H' has reached said lever G5 the electric circuit must again be closed, and said lug then upsets said lever G5, whereby the link G6 is shifted to the left and made to reset the lever G3 in the upright position, whereby the electrode G2 is again pressed down upon the electrode G' and the circuit again closed.

The sprocket-chain H and its relation tothe other mechanism of the machine are known in this art, and I deem it necessary to state herein on'ly that said chain is driven by the sprocket-wheel H2 on the shaft H3, Fig. l, and that said shaft is driven continuously from the powershaft K2, which latter is driven continuously during the operation of the machine by the belt-pulley K, iixed upon said power-shaft, as will be hereinafter described.

I, Figs. 2, 3, and 5, is an insulated standard set upon the frameA of the machine between the forcing-rolls E E' and the coilforming die E2.r4 On said standard is an arm l', reaching laterally nearlyto the point where the wire issues from the forcing-rolls and enters the coil-forming die. Said standard is connected with an electric circuit leading to the belt-shifting devices, and when the wire turns laterally between the coil-forming die and the forcing-rolls by breaking or merely doubling sidewise contact is made with said arm, whereby the circuit is closed. Said arm I' is preferably hinged to said standard in any suitable manner, as by the horizontal bolt I2, in order that said arm may be turned away from the forcing-rolls and the coil-form.- ing die when the latter are to be adjusted or removed.

The fifth and last of said correcting mechanisms-the one located between the coil- IIO forming mechanism and the coil-receiving mechanism-will be next described by reference to Figs. 2, 3,15, and 1G.

The insulated standard J is seated upon the frame A of the machine beneath the path of the coil going from the coil-forming mechanismtothecoil-receivingmechanism. Upon two screw-posts J', arranged in the same horizontal plane and parallel to the course of the path of the coil and secured to said standard, are hinged two arms J2, which normally extend upward at either side of the path of the coil. Said arms are preferably suitably coupled, as by gear-teeth J3, so that when one of said arms is turned the other arm will be simultaneously turned in the opposite direction. A contracting coiled spring J4 is joined by one end to one of said arms and by the other end to the other of said arms at points alittle above the hinges of said arms when the latter are in the upright position. Thus said spring will tend to hold said arms in the upright position. lf said arms are turned downward sufficiently to bring the points of attachment of said spring below the axes of said arms, the said spring will tend to draw said arms farther downward and hold them in such position. A set-screw J5 extends through one of the arms J2 and bears against the other of said arms and limits the approach of the upper ends of said arms of the coil. Opposite the coil-path each arm J2 has a curve J, extending away from said coil-path. This form is adopted in order that the coil-path may be substantially encircled by metahwith which the coil when leaving its path may make contact. l If, as already described, the coil meets resistance or leaves its path in the coil-receiving mechanism, so that it leaves its normal path between the icoil-forming mechanism and the coil-receiving mechanism, contact is made with 011e of the arms J2 and the electric circuit closed and the belt-shifting and brake mechanism instantly set into action. It is not imperative that the arms J2 be hinged so as to spread and fall away from the coil-path; but it is convenient to thus turn said arms out of the way when the coil is to be entered into the coil-receiving mechanism or the coil-receiving mechanism is to be adjusted or repaired.

The belt-shifting and brake mechanism will be next described. Said mechanism is also described and claimed separately in another application executed by me of even dale herewith.

K is a power-pulley- K is a loose or idle pulley. K2 is the powershaft. This-is journaled in the columns Kj K6, rising from the base A. Between said loose pulley and the adjacent column KG is a spur gear-wheel K3, which meshes into a cor responding gear-wheel K, seated on a shaft K5, journaled in said columns parallel to said power-shaft K2. At the left of the left-hand column K( said power-shaft supports a roller E', and immediately above said roller said shaft K5 supports a corresponding roller E, said rollers being ot' proper diameter to bring their peripheries into contact and being intended to be used for driving wire into the coil-forming dies of a wire-coiling machine or for any other similar work.

L is the belt. L is the yoke extending around the belt. L2 is a horizontal bar which supports said yoke. L3 L3 are horizontal parallel links hinged to said bar and the columns Ki K on vertical axes, so that said bar may be shifted endwise in a horizontal plane, whereby the yoke L is carried from one pulley to the other. As is well known, the tendency of such a pulleylbelt is to remain upon the pulley to which it has been shifted, so that usuallyr no mechanism need be employed to retain said belt in position on either of said pulleys. At the right of the right-hand column K6 two pins L1 stand upon the bar L2. Between said plus lies one arm of a bell-crank L5, which is suitably hinged at LG on a vertical axis. rl`he other arm of said bell-crank extends horizontally to the right over the loose pulley K and there supports an antifriction-roller LT. When the brake-shoe, to be hereinafter described, goes into action, it presses against said antifrictionroller L, whereby said bell-crank is turned upon its hinge the arm lying between the pins L4 LAl is moved toward the left, said arm bearing against the pin L4 at the left and through said pin forcing the bar L2, the yoke L', and the belt L to the left, the relative lengths of the arms of the said bell-crank being suich as to cause the bar L2 to move just far enough to shift the belt from the pulley K to the loose pulley K.

M is the brake. M is the shoe of the brake. M2 is a shaft extending loosely through the hubm of said brake M. Said shaft is parallel to the power-shaft- K2 and is located above and a little to the rear of the pulleys K and K and has one end rotatably secured in the standard M3, located at th-e leftof said brake. At the right of said brake said shaft extends through one end of the arm M4, and the other end of said arm surrounds the power-shaft K2. Said shaft M2 extends to the right of the arm Ml sufficiently to receive a crank M5, which crank is rigidly secured to said shaft, as by a set-bolt M6. Vithin the brake M the shaft M2 has the eccentric portion M7, the axis of such eccentric portion being at the rear of the axis of the main portion of the shaft M2. The purpose of said slot and set-screw is to IOO limit the rotation of the brake uponthe shaft M2, as will be readily understood by an inspection of the drawings.

E is a contracting-spring attached by its upper end to the rear portion of the brakehub, as by means of'a screw-bolt N, and by its lower end to the base of the standard M3 b y a screw-bolt N2. The tendency ot' said spring is to turn the rear portion ofthe hub of the brake downward and to turn the brake-shoe forward and upward. The rear l' ably secured in any suitable manner.

Vvdrawings show it so secured between two v"lugs'mf m4 on the portion of the arm M4 ad- T farther from the axis of the brake) and the location ofthe brake is such as to bring the forward end of said working face almost into contact with the [,)eripheryfot` the power-pulley when the brake is in its normal position, and said ecceutricity of the brake is sufficient to cause it to bind firmly upon said pulley when the brake-shoe is moved forward and upward. l

The working face of the brake may be covered with any suitable material adapted to make effective engagement with the periphery of the power-pulley and which may be replaced when worn ont. M10 is a sheet of such material secured at its front end by a screw m10 and at the rear 4by the screw M11. If so desired, an adjustable block M12, having a vertical slot m12, through which the screw M11 passes, may be interposed between said sheet and the brake. When the brake is to bear with greater force upon the power-pulley, said block may be -set lower, or it' the heel of the brake is found to extend too far on the axis ofthe brake said block may be moved slightly upward. Said pulley rotates in the direction of the arrow, and since it makes contact with said brake the latter is carried .forward by said pulley with a force greater than could be exerted by the spring N alone, and by reason ofthe eccentricity of the brake said shoe becomes wedged between the periphery o't' said pulley and the shaftM2. The forward and upward movement of said brake is limited by a lug HS, located on said brake, meeting a stationary stop M9, suitably secured, as upon the standard M3.

'lhe outer end of the crank M5 is detach- The jacent to the .shaft M2. Said crank is sufticientlyflexible to allow it to be sprung to to the right out of the space between said lugs. yWhen said crank has been thus released, it may be turned to partiallyT rotate the shaft M2 and release the brake by moving the axis of the latter, which is the axis of the eccentric M1, away from the power-pulley.

At the left-hand front portion of the brake a linger O extends upward adjacent to an armature O2, which is hinged at O2. From said armature a projection U extends to the right in suitable position to stand above the upper end of said finger when the brake has been turned downward and rearward out of engagement.- The spring N, as already described, tends to draw said brake forward and upward. The projection O forms a stop against such forward movement, and the brake is thereby held out of engagement, notwithstanding the action of the spring N, until the engagement between the finger O and the projection O' ceases. This occurs when the armature O2 turns toward the left upon its hinge. the left of said armature, shift the latter upon its hinge when the electric circuit in which said magnets are located and of which the wires O5 Ol5 form a part is closed and said magnets energizedvby the current then going through said circuit. When the finger O is thus released from the projection O', the brake is free to rotate in response to the tension of the spring N and said brake moves forward until it makes contact with the periphery of the powerpulley, and it is then carried forward by the force of said pulley (so far as said force is transmitted to said pulley by friction) added to the force of said spring. As already described, said brakeshoe is eccentric, its heel being the farther from the axis, sov that said brake becomes wedged more and more between the pulley and the shaft M2 until the resistance offered by thebrake becomes sufficientl t0 stop the power-pulley or until the lugM8 meets the stop M9. The portion of the brake forward of said working face recedes toward the axis of thebrake sufficiently to make room for the antifriction-roller L7 on the bell-crank L5. When the brake-shoe moves forward, said roller is pressed outward or forward by the working face of said brake-shoe, whereby said bell-crank is rotated upon its hinge and made to carry the bar L2 and the `yoke L and belt L to the left, said belt passing from the pulley K to the loose pulley K. An attendant may apply the brake and shift the belt in theV saine manner by manually pushing the armature O2 to the left. If it is desired to shift the belt without applying the brake, the bar L2 may be shifted manually.

As already stated, the beltshifter and brake mechanism are drawn into action when the electric circuit upon which the electromagnets are located is closed. In order that all the mechanism may be readily put back into normal position, said electric circuit should be again broken when the'machine is stopped. It will be observed that it would be inconvenient to reset the brake and hold it with the armature O2 without first denergizing the electromagnets.

P is a switch or circuit-breaker located at the left of the electromagnets. Said circuitbreaker is made an automatic means for breaking the circuit after ithas been closed by circuit-closing devices operating manlially or automatically for the stopping of the machine. Said circuit-breaker has a handle P, which extends between two pins P2 P2, rising from the bar L2. The relative arrangement of these parts is such that when the yoke L stands in front of the power-pulley the circuit-breaker P will make contacts to close the circuit and that when the bar L2 is shifted to the left to move the yoke L to the left, so as to stand in front of the loose pul- A pair of electromagnets O4, set at IXO ley K, the hinge of such circuit-breaker will be moved to the left sufiiciently to cause said circuit-breaker to break contacts.

It is to be observed that the bell-crauh L5 is not coupled to the brake. Hence the latter may be reset independently of the belt-shift ing mechanism.
